The utility model discloses an electromagnetic shielding plug-in card case, and relates to the technical field of electronic equipment cases, the electromagnetic shielding plug-in card case comprises a case body and a shielding panel used for sealing, the front part of the case body is oppositely provided with two flange modules, and the flange modules adopt a structure integrated with a handle. The shielding panel is fixedly installed on the rear portion of the case body, a PCB back plate and a plurality of DIN sockets are arranged in the case body, the DIN sockets are welded on the PCB back plate in an equidistant array mode, and the PCB back plate is fixedly connected with the upper cross beam and the lower cross beam. According to the utility model, the structure is simple, the shielding panel and the PCB back plate in the case are convenient to disassemble and assemble, the two shielding reeds are clamped at the two ports of the shielding panel, and the two shielding cloths are oppositely arranged on the inner side of the shielding panel, so that electromagnetic signals outside the case are effectively shielded at the seam of the shielding panel and the case body, and radiation to an internal circuit is avoided; signal transmission between electrical parts in the case is facilitated, and the anti-interference capability is high.

The invention relates to scoliosis screening, in particular to millimeter wave scoliosis screening equipment self-adaptive to the height of a human body and a working method thereof.The equipment base is fixedly provided with a lifting lead screw mechanism, the front side of the lifting lead screw mechanism is fixedly provided with a millimeter wave assembly, and a platform is used for detecting whether the standing posture of a to-be-detected person meets the requirement or not; after the movable case judges that the standing posture of the to-be-detected person meets the requirement, the height and back data of the to-be-detected person are collected through the optical camera, and the millimeter wave assembly is driven to be adjusted to the corresponding back position by driving the lifting lead screw mechanism. The millimeter wave assembly is driven by the movable case to emit millimeter wave signals to the back position, receive echo signals and send the echo signals back to the movable case, and the movable case generates millimeter wave images according to the echo signals and carries out scoliosis analysis; according to the method, the defects that radiation hazards exist, large-scale screening is difficult to carry out, and the screening efficiency and accuracy are low can be overcome.
